Summary: Features of Clavaria vermicularis include very fragile, white, cylindrical, slender fruitbodies that discolor yellowish from the top down, and growth in clusters or groups. Var. gracilis has a distinct pellucid stem and shorter spores 4.5-5 x 3-4 microns. Var. sphaerospora has spores nearly round at 3-6 microns or a few pyriform 4.5-5 x 3 microns. C. vermicularis is found in BC (in Redhead), WA (M. Beug, pers. comm.), OR (Zeller(2)), and CA (Arora), and is widely distributed in many parts of North America, (Phillips). Distribution includes PQ to NC, west to MN, Pacific Northwest to CA, (Lincoff), Europe (including France, Germany, Netherlands, United Kingdom), South Africa, China, Indonesia (Java), Japan, Sri Lanka, Australia, (Corner). There are collections from OR and ID at Oregon State University.
Fruiting body: 6-15cm high, 0.3-0.5cm wide, cylindric, becoming flattened; white, becoming yellow when old; grooved, (Phillips), 6-12(15)cm tall, 0.3-0.5cm wide, simple, occasionally forked once, often curved or flexuous [wavy], cylindric, then elongate fusiform [spindl
Flesh: very fragile, brittle; white, (Phillips), very brittle (Corner), flesh thin, very brittle or fragile, white, (Arora)
Stem: indistinct, cluster branched only at base, (Phillips), "indistinct, as a short, slightly narrower, sterile basal part", (Corner)
Odor: none (Corner), vaguely of green corn (Miller)
Taste: none (Corner), mild (Miller)
Microscopic: spores 5-7 x 3-4 microns, elliptic, smooth, (Phillips), spores 5-7 x 3-4 microns, elliptic or pip-shaped, smooth, thin-walled, generally without droplets "or very finely granular guttulate", sometimes with one droplet; basidia 4-spored, 30-45 x 6-8 microns, clavate, finely multiguttulate, without clamp connection; cystidia none; hyphae of flesh 3-16 microns wide, the cells 25-80 microns long (occasionally up to 150 microns long), the narrow hyphae with longer cells, longitudinal, compact, slightly constricted at septa, secondarily septate, thin-walled, without clamp connections, (Corner), spores 5-7 x 3-4 microns, elliptic to nearly round, smooth, (Arora)
Spore Deposit: white (Phillips, Arora)
Habitat / Range
often in huge masses in mossy soil under conifers, especially spruce, (Trudell), in tufts or clusters in moist soil, grass, fields, and woods, (Phillips), densely cespitose [in tufts] in tufts of 20-50, occasionally in tufts of 3-6 or gregarious, rarely single, among grass or on bare soil in fields and woods, (Corner), in tufts, clusters, or groups, on ground in woods or grassy places, (Arora), summer and fall (Miller)
Clavaria acuta is usually smaller, grows singly to gregariously (or more rarely in clusters), has a stem more differentiated in color, has wider spores, and has medallion clamp connections at the bases of the basidia, (Breitenbach).
